A serious contender for the ultimate summer watch title with an eye-catchy case material and extremely skeletonized movement. 
Coming in a trademark Executive collection case measuring 43 mm, the watch really stands out thanks to its lava-red image and texture slightly different on each piece. Made from a combination of ultra-light carbon fiber and red, marbled epoxy resin, – it is ultra-light, scratch-resistant and streamlined. The usual geometric perfection was left intact with a big X formed by four of the indexes framed in a rectangle inside a circle. Enlarged Roman numerals, marking the three and nine o’clock positions, are also bright red, while both hands are covered with Superluminova for nocturnal activity.
The Skeleton X Magma is powered by the UN-371 in-house caliber, an openworked hand-wound movement running at 3 Hz frequency. It features an extra-wide silicon balance wheel with nickel flyweights, a 4-day power reserve and is fully visible from the both sides of the case. While the exterior of the watch clearly lands more into the summer and leisure side of things, you’d better be careful with water, the amount of water resistance here is basic 50 meters. The watch comes on a black leather strap with black stitching The price is $25000.
